HPE Ezmeral Data Fabric Parameters
Describes Data Fabric parameters and their default values.
The following table lists user-configurable parameters and their default values. These
default values reflect those in the default configuration files, plus any overrides
shipped out-of-the-box in core-site.xml,
mapred-site.xml or other configuration files. You can override these
values by editing or adding them in mapred-site.xml or
core-site.xml using the -D option to the
hadoop jar command whenever you submit a job or set values
explicitly in your code.
